In this thesis we investigated the problem of formation of large-scale flow in the equilibrium relaxation model. The study focuses on weakly rotating, self-gravitating neutral fluid in the vicinity of a compact object, where gravitational effects of the compact object is neglected. For such model we employed the intermediate theory of gravity – the equations of Gravitoelectromagnetism. Carrying out the equilibrium analysis, for which we derived the Double Beltrami equation for the velocity field, we demonstrated the possibility of a catastrophic relaxation of equilibrium for the specific characteristic parameters of a chosen system. As a consequence, system undergoes the energy transformation. We have shown the possibility of a catastrophic formation of the large-scale velocity field while the conversion of the fluctuation energy into flow energy.
